Powder can be a difficult media to sample as it can vary widely in its constitution, ranging from thick sticky slurries, to fine powders to large particle sand like hard crystals or even larger particles. All types bring certain challenges in bringing the best solution to obtain a sample of the powder. There is certainly no one sampler which can be deployed. We have to consider each application we receive and design the sampler to suit the application. Coupled with how we might obtain the sample from the vessel, filter dryer, duct, chute etc is how we can safely dispense it so that the customer can transport it to be analysed. CRP has 20 years + of powder sampling experience and can tailor a design to suit the application.
Powder samplers use a thief to obtain the sample from the process, the thief can sometime be closed and the powder transported within it to be dispensed manually into a bag or similar. Or the powder is dispensed from the thief within the sampling system into a sample bottle or similar.
When it comes to filter dryers there can be moving parts within these and therefore we can supply actuated samplers which can be linked to the control system to prevent the sample thief being introduced into the dryer when it’s in motion.
Our powder samplers can be introduced into the vessel through the side or through the lid.
To help with specifying the right powder sampler for your application we have created this questionnaire.
